And the following new network system etc., it does not limit herein.
Based on above-mentioned terminal hardware structure and communications network system, SIM card initialization accelerated method of the present invention is proposed
Each embodiment.
It is the flow diagram that SIM card of the present invention initializes accelerated method first embodiment with reference to Fig. 3, Fig. 3.
In the present embodiment, the SIM card initialization accelerated method includes the following steps：
Step S110 monitors whether that the removing there are SIM card cache information in terminal buffers area refers in SIM card power down
It enables, the SIM card cache information includes the initialization files and chip identification code of SIM card；
In general, the basic process of SIM card initialization is：Restart when mobile terminal-opening or after being inserted into SIM card, mobile terminal
It is required for identification SIM card, first inquires chip identification code ICCID (the Integrate circuit card of SIM card
Identity), corresponding application specific directory A DF (Application Dedicated File) and is further selected, then
It reads in the EF files to mobile terminal caching under ADF, last SI reporting M card initializations complete event, to complete SIM card
Entire initialization procedure.And after SIM card power down, mobile terminal can fall clearly the SIM card information in caching, and wait know card next time
When, repeat the above process.
The case where usual SIM card power down, is broadly divided into three kinds：One is SIM card failure problems, namely fall card；It is a kind of
It is that SIM card is pulled out, namely pulls out card；Another kind is mobile terminal shutdown.When any case occurs among these, mobile terminal
The SIM card information in caching will be disposed, to ensure the data safety of SIM card account.
The process initialized by above-mentioned SIM card is it is found that there are nothing but following two realizations in the initialization speed for accelerating SIM card
Mode：
Realization method one：Accelerate the execution speed of each operating procedure in initialization procedure；
Realization method two：Reduce the operating procedure in initialization procedure.
Obviously, the first realization method executes increasingly complex and difficult with respect to the first realization method, and not necessarily
There is larger effect.Therefore, the present embodiment preferably promotes the initialization speed of SIM card by the second way.
It is not reduction truly it should be noted that in the present embodiment when accelerating SIM card to initialize speed
Operating procedure in SIM card initialization procedure, but be directed to for the special applications scene of SIM card, namely for mobile whole
End re-starts the initialization operation process of SIM card this special applications scene when knowing card next time.
In general, in mobile phone terminal, SIM card corresponds to phone number, and user usually can't frequently change the hand of oneself
Same SIM card can be used for a long time in machine number namely mobile phone terminal, and therefore, almost SIM card each time initializes also substantially
All it is corresponding same SIM card, therefore, as long as SIM card had carried out initialization, and remained the SIM card information of caching,
Then mobile terminal, which subsequently knows card, can not do SIM card initialization, or only do a few SIM card initialization step, from
And it can substantially accelerate the initialization speed of SIM card.
Step S120, and if it exists, then forbid responding the clearance order；
Considering for application scenarios is initialized based on above-mentioned SIM card, in the present embodiment, in SIM card power down, monitors whether to deposit
The clearance order of SIM card cache information in terminal buffers area, if there is the clearance order for SIM card cache information, then
Forbid responding the clearance order, to retain the SIM card information in caching, to avoid re-starting again when knowing card next time
SIM card initialization operation.
In the present embodiment, clearance order specifically by mobile terminal itself initiate, for example, when mobile terminal for a long time not with
When SIM is communicated, then SIM card cache information clearance order is automatically initiated.
In addition, the present embodiment is unlimited for forbidding the realization method for responding clearance order.For example, by directly removing being made to refer to
It enables failure and forbids responding clearance order to realize, or do not execute clearance order by indirect control terminal buffers and forbid to realize
Respond clearance order.
Step S130 when electric on the sim card, reads the chip identification code for powering on SIM card, and judges to power on the core of SIM card
Whether piece identification code and the chip identification code stored in terminal buffers area are consistent；
Step S140, if unanimously, SI reporting M card initializations complete event.
In the present embodiment, the case where SIM card powers on, is broadly divided into two kinds：It is switched on again after shutting down one is mobile terminal；Separately
Restart again after being inserted into SIM card one is mobile terminal shutdown.
In the present embodiment, when SIM card powers on, which had both been likely to be new SIM card, it is also possible to be old SIM
(namely the SIM card used before power down) therefore powers on the chip identification code of SIM card to reading, then judges to power on SIM card again
Chip identification code and the chip identification code that is stored in terminal buffers area it is whether consistent, namely judge currently whether power on SIM card
For the SIM card used before power down.
If the chip identification code of SIM card compares consistent, illustrate that the current SIM card that powers on is exactly the SIM used before power down
Block, under such application scenarios, the SIM card information retained in caching can be directly used, to reduce the operation in initialization procedure
Step saves the initialization time of SIM card.Therefore, it can directly SI reporting M card initializations completion event namely SIM card be in
Ready states.
Optionally, in one embodiment, when electric on the sim card, if powering on chip identification code and the terminal buffers area of SIM card
The chip identification code of middle storage is inconsistent, then is initialized according to the initialization flow of acquiescence to powering on SIM card.Namely if
The chip identification code comparison of SIM card is inconsistent, then illustrates currently to power on the SIM card that SIM card is new, under such application scenarios, need
It to be initialized according to the initialization flow of acquiescence to powering on SIM card.Since the number that such application scenarios occur is especially few,
Therefore, it sees on the whole, the present invention program is still to accelerating SIM card initialization to have larger effect.
Optionally, in another embodiment, when electric on the sim card, if powering on the chip identification code and terminal buffers of SIM card
The chip identification code stored in area is inconsistent, then removes the SIM card cache information in terminal buffers area.
As shown in figure 4, in SIM card power down, retain SIM card cache information in terminal buffers area；As shown in figure 5,
When identical SIM card powers on, the SIM card cache information in direct using terminal buffer area avoids carrying out identical SIM card again just
Beginningization, to improve the initialization speed of SIM card.
In the present embodiment, in SIM card power down, monitor whether that there are the removings of SIM card cache information in terminal buffers area
Instruction, and if it exists, then forbid responding the clearance order, to retain initialization files and chip when last SIM is powered on
Identification code.When electric on the sim card, read the chip identification code for powering on SIM card, and judge to power on the chip identification code of SIM card with
Whether the chip identification code stored in terminal buffers area is consistent；If it is consistent, namely when the corresponding SIM card of cache information with it is current on
